CONCRETE STEP.

Application led June 14, 1923. Serial No. 645,247.

To all 'whom it may concern.'

Be it known that l, HARRY A. DALY, a citizen of the United States,residing at Philadelphitu'in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inConcrete Steps, of which the following is a specification.

My invention relates to concrete steps and more particularly tointerlocking concrete steps adapted' for use in stoops or stairways. Theobject is to provide steps made of concrete which are simple and durablein construction, easily and cheaply manufactured and easily assembledinto a stoop or stairway.

This object, and other advantageous ends which will be describedhereinafter, l attain in the following manner, reference being had tothe accompanying drawings in which- Figure l is a central sectionthrough a stoop constructed of my improved steps,

Figure 2 a perspective view of a step constructed in accordance with myinvention,

Figure 3 a fragmentary perspective view of the landing step with thesecuring means,

Figure 4 a perspective View of a reinforcing cage constructed inaccordance with my invention,

Figure 5 a longitudinal central section through Figure 4, and

Figure 6 a section on line 6--6 of Figure 5.

Referring to the drawings, 1 indicates a wall of`a'-building, such asthe wall under a doorway, having stoopwalls 2 extending therefrom anddisposed at the opposite sides of the stoop. My improved steps 3 aresuperposedl and mounted on the walls 2. nlhe steps are locked to eachother by interlocking means which comprise a shoulder 4 in the upper;meeting corner of one stepfor receiving the lower meeting corner of thesuperposed step, and having vertically projecting interlocking bars 5adapted to take into vertical holes 6 in the corner of the in shape andhas an arched part 12. Wire mesh 13 of any suitable character is securedto the upper and lower supports 10 and 11 to form a cage as shown inFigures 4, 5 and 6. The arched wire mesh 14 secured to the the other andthe last step will hold the stoop or stairway in position by beingsecured to the wall as shown in Figure l. The reinforcing cagestrengthens the steps and prevents cracking. rlhe arched under side ofthe step and the arched part of the cage make the steps light and rigid.

lWhile l have described my invention as taking a particular form, itwill be understood that the various parts of my invention may be changedwithout departing from the spirit thereof, and hence l do not limitmyself to the precise construction set forth, but consider that l am atliberty to make such changes and alterations as fairly come within thescope of the appended claims.

Having thus described my invention, what l claim as new and desire tosecure by Letters Patent is 1. il stoop including conci-cte steps, themeeting corner of one step being provided with holes, the meeting cornerof the other step being provided with a shoulder for receiving thecorner of the first step, and vertical bars projecting from theshoulders and adapted to take into the holes of the first step.

Q. A stoop including concrete steps provided with an arched art in theunder side, the meeting corner of one step being proi vided with holes,the meeting corner of the other step being provided with a shoulder forreceiving the corner of the first step, and vertical bars projectingfrom the shou der and adapted to take into the holes of the first step.

3. A reinforcing frame for concrete steps including a rectangular upperwire support; a rectangular lower wire support having an arched part;Wire mesh secured to the upper and lower Wire supports adapted to coverJche supports and form e cage, and interlocking bars secured to theupper Wire support and having one of their ends projecting upwardly.

4. The combination with e Wall of a ooni crete landing step; boltsembedded in the step and having their ends extending through the Wall; aplate spanning the ends, 10 and means for securing the bolts to theWall. In testimony whereof I have signed mynzune to this specificationin the presence of two subscribing Witnesses.
